IMPROVEMENT IN SAFETY DERRICK-IAMPS.

The Schedule referred to in theseLetters Patent and making partrofthelame To all whom 'it may concern g l i Be it known that I, J ONATHANDILLEN, of Petroleum Centre, in the county of Venango and State of'Pennsylvanimhave invented certain new and useful Improvements n1 SafetyDerrick-Lamps, and thefol-v lowing is a fnll,clear, and exactdescription ofthe same,

reference being had. to the accompanying drawings making a part of thisspeciiication, in \vhich-.

v Figure l represents an outside view lof vthe lamp as an article ofVlnanufacture :l-nd'trade, ready for the marke-t. i l

Figure 2, a sectional view vertically through the center of the lamp,showing the inode of securing and Ventilating the lid 0r cover and thewick-tubes, 86o.

My invention relates to hanging-lamps or torches for-illuminating placesout of doors, especially in and about derricks, and machinery in the oilregions, whereby explosions are more dangerous and destructive to lifeand property than in most otherplaces; and

It' consists in making the body of the lampwith two or. more wick-tubes,cast all together of malleable iron, 'or other strong and durable metal,with .lugs or ears on which to hook a clamp, for securing rmly the lidto the body.

Also in providing a ventlating-tube and shield in the cover, for theescape of gas, and the-double flange,

Afor holding the packing between the lid and body.

Tolenable others to fmake and use my invention, I willl describe it.more fully, referring to the drawings and the letters marked thereon.

- The body A may be made of malleable cast-iron,

or other durable tenacious metal, cast with the wicktubes B B on.

.Also the ears a a, for the bail to be inserted, and y the. lugs or hooks,bl b, forthe clampfbar D to hook onto, to secure the cover E firmlyonftl'ie-lmdy by a y thumb-screw, (l, in .the center of the clamp-barvD.

' The lid or cover E is provided with a double-rim' c e',`in which therubber gasket f f, or other 'elastic packing, is secured, so that thecover will fit on gastight, -thc cover being4 inade crowning, andthickened.

up in the central portion to give it strength where the clamp-screw cl,bears upon inland' is providedA on one side of the center with a smallvent, through a tube h, on one side o f which'isgi shield, t,

On the outside of the bodyofv the lamp A'Vtwo or more loops or eye-s jjniaybe cast, in which to insert' a rod'F, or a hook, or any suitableinstrument for trimming the lamp. j

Any desired number of wick-tubes maybe made: and used,v and the. gasgenerated by the heat-oi' the tubes, within the body of the lamp, willescape at the vent, and, if it takes firevat the tube, it will burnfree#r ly and help to illuminate the place, Awithout the slight-A I estdanger of' exploding the lamp or setting lire tothe derrick. i 1
